I just tried the cooling system additive that is supposed to bring down engine temp and lube the coolling system and help prevent thermistat sticking. Well, so far with only 10kms with it in, I am impressed. Temp is 1.5 letters to the left of where it was in the word NORMAL. But we'll see. Hopefully it will continue to work after 10 000kms.
